Our take
Castor’s cloud-based clinical data management platform allows clinical trials to be carried out faster and in a more decentralised and patient-focused manner. Some of the biggest roadblocks to successful clinical trials are the length of time they can take, a lack of diversity in participants, and a simple shortage of trial subjects. Castor’s tech allows researchers to overcome these obstacles by more easily capturing and integrating data.
Castor, along with other med tech startups like Thread and Florence garnered praise during 2020 as a lot of medical research transitioned to virtual. In a clinical trials market that’s worth over $40 billion worldwide and still growing, the fact that Castor counts the WHO in its customer base is encouraging.
Backed by Eight Roads Ventures and F-Prime Capital, Castor is aiming to use its funding round to continue product development, data gathering, and increase its manpower, with a view to expanding operations beyond the US and into Asia.
